Searchers
Flowra gives searchers what Solana has never had: permissionless, standardized access to orderflow. No privileged relationships, no private deals. Subscribe to the stream, find your edge, and win by bidding.
What you get
An open, standardized stream
Pending transactions from all participating validators, deduplicated and delivered over a single gRPC interface. One integration covers the whole Flowra validator set. See Orderflow Stream.
Auctions every 50 ms
Mini-auctions close every 50 ms, up to eight rounds per Solana slot. Within a window, the highest tip wins among non-conflicting bundles; you are racing bids, not nanoseconds. Mechanics: Auction Mechanics.
Atomic, all-or-nothing bundles
Bundles execute in order and in full, or not at all. Failed bundles never land, so multi-leg strategies carry no partial-execution risk and no wasted fees on reverts. See Bundles.
Strategy confidentiality
The orderflow is open; your bundles are not. Submissions go point-to-point to the Block Engine and are never exposed to other searchers or a public mempool.
Simple economics
The protocol fee is 5% of tips. No subscriptions, no per-seat access fees, no paid data tiers.
